Specification forming part of Letters Patent No. 58,304, dated September' 25, 1866.

To all whom fit may concern:

Be it known that we, CYRUS W. SALADEE and VILLIAM VEACH, of Newark, county ot' Licking, State of Ohio, have invented a new and Improved Mode of Constructing a Mechanical Movement; and we do hereby declare that the i'ollowin g is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature-of our `invention consists, first, in the peculiar arrangement, hereinafter shown and described, ot' supporting the pitman K across or upon a line with the center of the drivingwheel A; and, second, in that ot' the peculiar arrangement of the corrugated driving-wheel A, in combination With the pitman K,and friction-rollers B B', so that at one revolution ofthe shaft supporting the drivingwheel the number of the strokes of the pitman is increased to any requisite degree of speed.

AIn the drawings, F1g.l represents a side elevation of the parts employed, and Fig. 2 is a top view of the same.

XVe intend applying our invention to mowing-machines, to impart an increased motion to the cutter-blade; also, for driving` up-anddown jig-saws. We can also, by the application of our improved motion, construct a most Y cheap and simpl y-constructed sewing-machine.

In short, we intend using it wherever a rapidly-workin g pitm an isdesirable in machinery.

By the use of this motion we can construct a mowing-machine with just about one-halt' the usual number of working-parts employed.

By reference to Plate 2, it will be seen that only two cog-wheels are required to transmit a rapid motion to the cutter-blade. The driving-wheels S' ofthe mower (shown by the drawing on Plate 2) are cast without eogs, a single cog-wheel, A', being secured upon the axle B2 of the machine ot' as large diameter as the case will admit of, and which is made to mesh into the small cog-wheel A2 on the end of the driving-shaft E, when. at each revolution of the latter, the cutter-blade makes ten strokes, or even a greater number, if the number ot' corrugations on the driving wheel are increased. Y

We construct our improved mechanical movement substantially as follows: We first determine the length of stroke we wish to give the pitman K, which will indicate the diameter of driving-wheel A. For example, we will say the stroke ofthe pitman shall be three inches. To get this, we draw the diameter of the WheelA, as indicated by the circle red line S. We now space oft' this circle to the number of strokes we want the pitman to make to each revolution of the driving-Wheel A. This done, we draw the lines across the Y driving-wheel A and friction-rollers B B are made to work, substantially in the manner clearly shown in the drawings.

The frame C of the pitman K is made to slide upon the center shaft E of the drivingwheel A, by means of the oblong slot o, (see Fig. 1,) so that the stroke of the pitman shall be exactly the same at any point of connection at its outer end, whether Working at an angle, as represented by Fig. l, or on a line parallel with the base-line X, or perpendicular.

The friction-rollers B B are secured within the frame of the pitman, in combination with the driving-wheel A, substantially as reprel sented in the drawings, Figs. l and 2.`

Onthe front end t the pitman-frame G is cast solid the bilge P, into which is screwed the round wrought-iron pitman-rod K, and secured in position by the set-screw N. There are a variety of wa 's in which this pitman may be held in a central position across the lcenter of the drivingwheel A, but we now think that t-he manner here shown is best. We therefore Ywish `it to be distinctly understood that we do not limit our claim to theprecise manner here shown ot' maintaining the pitman K across the center of the driving- Wheel A, and working in combination therewith, as any other device that will, hold it ondriving-Wheel A, discarding the use of the frame C, shown in Fig. 2, Fig. 3 being a top View of the arrangement last named. E is the shaft of the driving-Wheel, A the wheel, G and K the pitman. B B' are the shoulders, made solid to the pitman, and made to serve as a substitute for the rollers B B in Figs. 1 and 2. E2 is a thin washer slipped over the shaft E, and against which the nut or tap E3 is screwed to hold the whole in position.

Fig. 2, on Plate 2, illustrates another man' ner of connecting pitman K to the driving.

wheel A. In this illustration we have a double pitman, K K, connected to the frame C, and supported in the bearings G2 and C2. In place of the friction-rollers B B, as shown on Plate 1, We forni the projeetions C and (l, in connection with the frame C, as shown in the drawings.

We will here remark that it' noise and clat ter attend the Working parts of the friction -rollers B B', Figs. 'l and 2,' Plate l, and driving-Wheel A, the rollers may be set in sliding boxes, and kept pressed tightly up against the driving-wheel by means of indiarubber or spiral springs interposed bet-Ween the sliding' boxes and the frame of the pitman.

Having thus fully described our invention, what we claim as new, and desire t0 secure by Letters Patent, is-

1. Broadly, supporting and operating the pitman C K, Figs. 1 and 2, Plate 2, across and upon a line with the center E of the oorrugated driving-Wheel A, substantially as and for the purpose set forth.

2. The arrangement ofthe corrugated wheel A, in combination with the pitman C K, and friction-rollers B B', or their equivalent, in the manner and for the purpose substantially as shown and described.

In testimony that We claim the above we hereunto subscribe our names.
